IMPROVEMENT- IN LAMPS.

Specication forming part of Letters Patent No. 136.553, dated March 4, 1873.

To all whom -t may concern:

Be it known that I, GEORGE H. SIMMONS, of Bennington, in the county of Bennington and State ot' Vermont, have invented a new and valuable Improvement iu Lamps; and I do hereby declare that the tbllowing is a full, clear, and exact description ot' the construetion and operation ot' the same, reference being had to the annexed drawing making a part of this specitication, :and to the letters and iigures ot' ret'erence marked thereon.

Figures l and 2 show my lamp arranged for filling with oil. Figs. 3, 4, and 5 are moditications ot' my lamp.

My invention has relation to kerosene and other lamps; anti consists in the construction and novel arrangement ot' a catch-funnel and sliding feed-tube, whereby the oil is prevent` ed from getting on the outside ot' the lamp or coming in contact with the cement by which the collar is fastened theseV parts being arranged to be operated with great convenience, all as is hereinatter described.

In the accompanying drawing, the letter A desi gnatesa lam p-t'ount. B represents a lampburner, at the base ot which is arranged the screw U. D indicates a wick. E designates the spout of a tlling-can, and, in connection with the arrows-which show the course ot' the oil-aids to illustrate the opera-tion ot' tilling the lamp. F represents the introverted edge ot' the catch cup or funnel T, which aids in preventing the escape ot' oil. G indicates `the inner or feed tube, at the upper end and upon the inner side of which is arranged the screw-thread H. J J designate apertures through and near the upper end of tube G, of suitable size and number, through which the excess or overflow ot' oil escapes into the lamp, and is saved. K K indicate apertures through the tube G, of suitable size and number, and suitably located, through which the oil passes when iilling the lamp, as shown in Fig. 1. L designates an annular groove near the lower end of the tube U ot' the catchfunnel, into which expand the springs N N when the tube. G is raised, as when illing a lamp. M M indicate beads on'the springs N N, formed to correspond with and t into the annular groove L in the tube U. The springs are of suitable dimensions, located at and forininga part 0r the whole of the lower end ot tube G when said tube is used in connection with tube U, as in Figs. l, 2, and 3. The ot'- iice of these springs is to support and holdup the burner, chimney, and tube G for the purpose of filling the lamp, as shown in Figs. l and 2. rlhe lower ends ot' the springs should be slightly bent outward to prevent the tube G from being pulled out of tube U. O designates the colla-r, fastened tothe neck ot' the lamp by the cement P. Q indicates the screw or joint between the collar O and catch-funnel tube U. It represents a conical expansion ot' the feed-tube, which lits the conical seat S in the funnel when said feed-tube is pushed down to place, as shown in Fig. 3.

Figs. 4 and 5 illustrate the manner in which that part ot'my invention operates which relates t0 catching and conveying back into the lamp the excess or overiiow oi' oil, and preventing the saine, as well as the oil which may rise in the wick, from coming in contact with either the cement or with the screw in the collar, and working out through thc said screw to the Outside Ot' the lamp. This part ot' my device may be attached to lamps in cases where my feed'- ing arrangement or device may not be used.

In Fig. 4 the catch-cn p is illustrated as torming a part ot the. structure ot' the collar.

In Fig. 5 the catch-cup. is illustrated as form- -ing a part ofthe structure ot'the burner, in which l case the tube U would be a continuation ot' the base of the burner.

The several parts ot' my invention may be constructed ot' any suitable material.

In lamps as ordinarily constructed more or less oil finds its way out through the screwjoint between the collar and the burner. The oil also comes in contact with and softens the cement with which the collars are fastened to the necks ot' the lamps. In my invention all of the oil is deposited in the la-mp at a point sufficiently low, and there controlled in such a manner that none can escape except by combustion. AThere is no need of nnscrewing or removing the burner, globe, or chimney in lilling the lamp.

I claiml. The sliding feed-tube G, having the expansion R, in combination with the funneltnbe, having a suitable seat, S, for said expansion, substantially as specited.

2. The vertically-sliding feed-tube G, hav- 2 Haasse in g at its upper end and middle the apertures J and K, and its lower end slitted to form expanding springs N and bead M, substantially as shown, and for the purposes set forth.

3. The catch-funnel tube T, constructed as described, and shown in Fig. 4, consisting of the collar 0, tube U, and screw-threaded collar H, with openings.

4. The combination of the sliding feed-tube G, provided with the apertures J and K and expanding springs N, and catch-funnel tube T,

provided near its lower end with4 the annular groove L, substantially as specified.l

5. The funnel-tube U, having an annular groove, L, substantiallyr as specified, and for the purpose described.

In testimony that I claim the above I have hereunto subscribed my name in the presence 'of two witnesses.

Witnesses: GEORGE H. SIMMONS.
